Content
The double jump is a name given to a quick series of two jumps.
Conditions
- The second jump must be triggered within 400ms of the previous jump's execution
- If, at the beginning of a regular jump, the player's Z velocity is u units per second, then the player's Z velocity should be 1.5 * u per second when initiating a successful double jump. This is an initial value and will require tweaking. Discussion page for ideas / suggestions -- Defrag
Please note that doubling the Z velocity will not double the jump height, as gravity affects the calculations.
If you really care about why this is: Velocity Versus Height.
Applications
Double jumps can be performed in a variety of ways. Some examples:
- Jumping from a low area onto higher ground, thus enabling the second jump to occur quickly.
Example 1: Jump from the flat area below the shutdown2 ramp, then immediately jump into the ramp to trigger the double jump.
Example 2: Jump onto a box top from the floor then jump immediately once more.
- Jumping against low ceilings or overhead objects to force contact with the ground more quickly.
Example: Jump under the monkey_l pit ramp, hit the underside of it and then bounce back into the ground, jumping again when touching the ground. Do so in a way that one is no longer under the ramp when performing the second jump.
- Jumping onto a ladder's lower rungs then immediately dismounting and then jumping again once hitting the ground.
Example: Jump onto the shutdown 2 ramp room ladder, dismount and head towards the elevated switch exit, perform a second jump and bounce up to the elevated switch entrance.
- Double jumps can be combined with bunnyhopping, concs and trimps to form very potent moves.
Double jumps can not be triggered multiple times in a row to create cumulative effects. I.e. no triple or quadruple jumps. We may have to tinker with the order of trimp & double jump velocity being added depending on how effective this is.
